In 2005 four outstanding multiple burials were discovered near Eulau, Germany. The 4,600-year-old graves contained groups of adults and children buried facing each other. Skeletal and artifactual evidence and the simultaneous interment of the individuals suggest the supposed families fell victim to a violent event. In a multidisciplinary approach, archaeological, anthropological, geochemical (radiogenic isotopes), and molecular genetic (ancient DNA) methods were applied to these unique burials. Using autosomal, mitochondrial, and Y-chromosomal markers, we identified genetic kinship among the individuals. A direct child-parent relationship was detected in one burial, providing the oldest molecular genetic evidence of a nuclear family. Strontium isotope analyses point to different origins for males and children versus females. By this approach, we gain insight into a Late Stone Age society, which appears to have been exogamous and patrilocal, and in which genetic kinship seems to be a focal point of social organization.

With the rise of ancient DNA studies in prehistoric archaeology, terms such as matriliny and patriliny are commonly used in scholarly literature. From a sociocultural anthropological perspective, however, the two terms are not as simple and unproblematic as is widely accepted among archaeogeneticists. Matriliny and patriliny are umbrella terms for societies with a wide range of political and kinship practices, with or without a state. Moreover, archaeogenetic literature has assumed specific associations with matrilineal and patrilineal descent that are not supported by sociocultural anthropology. To properly understand the diversity of human sociopolitical forms in both the deep and recent past, archaeology – in its broadest sense, including archaeogenetics – must avoid essentializing prehistoric communities without exploring the empirical nuances that are well documented ethnographically. Finally, the article calls for more engagement in debates on kinship and sociopolitical organization in prehistory from sociocultural anthropological perspectives.
Kinship Determination in Archeological Contexts Through DNA Analysis
Frontiers in Ecology and Evolution
Knowing kinship relations between individuals in archeological contexts is of great importance to understand social habits and structure in past human communities. Archeological and anthropological analyses of burial sites and skeletal remains often allow us to infer connections between individuals, but only genetic analysis can provide a sound determination of kinship. Several case studies are now available in the literature that show the potentiality and limitations of different methodological approaches based on ancient DNA (aDNA). Both experimental and computational strategies for kinship estimation on ancient samples are described in this review and we argue that, within a multidisciplinary approach, kinship inference contributes to the understanding of the biological and cultural patterns that characterized past societies.

The analysis of ancient DNA recovered from archaeological remains can be used to reconstruct kinship among the occupants of a necropolis and provide a more detailed portrait of the community considered. Such palaeogenetic analyses have been conducted on sarcophagi excavated from the Merovingian necropolis in Jau-Dignac et Loirac (7the8th century AD, Aquitaine, southwest France). The genetic study consisted of the analysis of mitochondrial DNA and nuclear STRs (Short Tandem Repeats) from nine skeletons deposited in three grouped sarcophagi. Only data concerning the mitochondrial genomes could be obtained, and six different mitochondrial lineages were retrieved from eight samples. Our analyses permitted a high confidence characterisation of maternal relationships between individuals deposited in the same sepulchre. These results are important and novel for the period and region and argue that individuals were grouped inside sarcophagi according to relationship criteria. The presence of perinatal remains in one sarcophagus was particularly striking because access to this type of funerary structure during this period was generally reserved for older children. Moreover, we demonstrated genetically that the perinatal remains were not related maternally to two women found in the same sarcophagus (whereas the maternal relationship between the two young women could be determined), and we proposed different possible explanations for this unexpected observation. Overall, archaeological, anthropological and genetic data suggest that the Jau-Dignac et Loirac necropolis groups together the closely and distantly related members of a High Middle Ages familia. Our ancient DNA analyses note the important contribution of palaeogenetic analyses to archaeological kinship studies.
Extensive pedigrees reveal the social organization of a Neolithic community
Nature, 2023
Social anthropology and ethnographic studies have described kinship systems and networks of contact and exchange in extant populations1–4. However, for prehistoric societies, these systems can be studied only indirectly from biological and cultural remains. Stable isotope data, sex and age at death can provide insights into the demographic structure of a burial community and identify local versus non-local childhood signatures, archaeogenetic data can reconstruct the biological relationships between individuals, which enables the reconstruction of pedigrees, and combined evidence informs on kinship practices and residence patterns in prehistoric societies. Here we report ancient DNA, strontium isotope and contextual data from more than 100 individuals from the site Gurgy ‘les Noisats’ (France), dated to the western European Neolithic around 4850–4500 bc. We find that this burial community was genetically connected by two main pedigrees, spanning seven generations, that were patrilocal and patrilineal, with evidence for female exogamy and exchange with genetically close neighbouring groups. The microdemographic structure of individuals linked and unlinked to the pedigrees reveals additional information about the social structure, living conditions and site occupation. The absence of half-siblings and the high number of adult full siblings suggest that there were stable health conditions and a supportive social network, facilitating high fertility and low mortality5. Age-structure differences and strontium isotope results by generation indicate that the site was used for just a few decades, providing new insights into shifting sedentary farming practices during the European Neolithic.

We present a high-resolution cross-disciplinary analysis of kinship structure and social institutions in two Late Copper Age Bell Beaker culture cemeteries of South Germany containing 24 and 18 burials, of which 34 provided genetic information. By combining archaeological, anthropological, genetic and isotopic evidence we are able to document the internal kinship and residency structure of the cemeteries and the socially organizing principles of these local communities. The buried individuals represent four to six generations of two family groups, one nuclear family at the Alburg cemetery, and one seemingly more extended at Irl-bach. While likely monogamous, they practiced exogamy, as six out of eight non-locals are women. Maternal genetic diversity is high with 23 different mitochondrial haplotypes from 34 individuals, whereas all males belong to one single Y-chromosome haplogroup without any detectable contribution from Y-chromosomes typical of the farmers who had been the sole inhabitants of the region hundreds of years before. This provides evidence for the society being patrilocal, perhaps as a way of protecting property among the male line, while in-marriage from many different places secured social and political networks and prevented inbreeding. We also find evidence that the communities practiced selection for which of their PLOS ONE PLOS ONE | https://doi.org/10.1371/journal.pone.
Genealogy: The Tree Where History Meets Genetics
Genealogy
Although biological relationships are a universal reality for all human beings, the concepts of “family” and “family bond” depend on both the geographic region and the historical moment to which they refer. However, the concept of “family” can be determinant in a large variety of societies, since it can influence the lines of succession, inheritances and social relationships, as well as where and with whom an individual is buried. The relation between a deceased person and other members of a community, other individuals of the same necropolis, or even with those who are buried in the same tomb can be analysed from the genetic point of view, considering different perspectives: archaeological, historical, and forensic. In the present work, the concepts of “family” and “kinship” are discussed, explaining the relevance of genetic analysis, such as nuclear and lineage markers, and their contribution to genealogical research, for example in the heritage of surnames and Y-chromosome, as we...
